Although necessarily brief due to editorial limitations, this paper attempts to elaborate on the nonverbal categories established by Ekman and Friesen (1969), inspired partly by Efrón (1941), in the belief that, although they referred only to "any movement or position of the face and/or the body", the functions that are studied are perfectly common to other nonverbal categories as well. In addition, besides some terminological modifications, body-adaptors are added, while time markers, echoics, kinephonographs, externalizers and identifiers are incorporated as illustrators.
